Common causes of this issue include outdated or corrupt drivers, which are essential for the proper functioning of Bluetooth and audio devices on your system. Other triggers for the bthhfenum.sys BSOD may be general hardware conflicts or malfunctions, and occasionally, system updates that were incomplete or introduced compatibility problems. This article discusses solutions to resolve this issue.
1. Run SFC and DISM
The problem could be due to corrupted system files; running SFC (System File Checker) and DISM (Deployment Image Servicing and Management) utilities is recommended to address this. These tools scan for corrupted files, perform repairs, and restore system integrity.
2. Clean Boot Windows
Third-party services can interfere with system files and cause issues. To determine if they are the cause, try performing a clean boot of Windows; this stops all non-Microsoft services from running at startup, which might resolve the problem.
3. Update And Reinstall Drivers
Outdated or corrupted drivers might also be the root cause of this issue. Updating drivers could solve the problem, and it’s especially recommended to reinstall Audio and Wireless drivers since they are connected to the problematic file.
4. Update BIOS
Updating the BIOS can resolve the bthhfenum.sys BSOD problem as it updates the motherboard’s firmware to the latest version. This can improve hardware compatibility, fix known bugs, and enhance overall system stability, including the management of Bluetooth and audio functions that rely on the bthhfenum.sys driver.
